INDIAN GEOGRAPHY

Detailed explanation-1: -Continental crust is indeed “granitic”, and has the general composition typical of granitic rocks, made up of mostly aluminium silicates (the SiAl).

Detailed explanation-2: -Granite is a light-colored plutonic rock found throughout the continental crust, most commonly in mountainous areas. It consists of coarse grains of quartz (10-50%), potassium feldspar, and sodium feldspar. These minerals make up more than 80% of the rock.

Detailed explanation-3: -The continental crust is the layer of granitic, sedimentary, and metamorphic rocks, which form the continents and the areas of shallow seabed close to their shores (continental shelves).

Detailed explanation-4: -Granites form a major part of the continental crust, forming small stocks and batholiths (large emplacements of igneous rocks), commonly found in mountain ranges such as the Himalayas where continental collision has taken place.

Detailed explanation-5: -Granite, which makes up 70–80% of Earth’s crust, is an igneous rock formed of interlocking crystals of quartz, feldspar, mica, and other minerals in lesser quantities. Large masses of granite are a major ingredient of mountain ranges.
